A performance test to monitor rehabilitation and evaluate anterior cruciate ligament injuries
- 1986

- A performance test simulating components of sports was devised to evaluate dysfunction after ACL injury. The test included a one-leg hop, running in a figure of eight (straight running and turn running measured separately), running up and down a spiral staircase, and running up and down a slope. Twenty-six men with ACL injury, most of them soccer players, and 66 uninjured male soccer players were studied. Patients with ACL injury performed significantly less well than the uninjured players. Test items of special interest were turn running in the figure of eight, stair running, and slope running, all of which place high demand on the knee. It is concluded that a performance test of this design is useful for monitoring rehabilitation and for evaluating the patient's condition. Before sports can be resumed at the original level, normal strength and normal performance should be regained.

Strengthening exercises for old cruciate ligament tears
- 1986
-
In: Acta Orthopaedica Scandinavica. - : Medical Journals Sweden AB. - 0001-6470. ; 57:2, s. 130-134

Journal article (peer-reviewed)abstract
- Fifty-three consecutive patients with troublesome old cruciate ligament lesions underwent a 3-month thigh and calf muscle training program. Before training, the diagnosis was established by arthroscopy and clinical examination under anesthesia. Significant improvement in strength, performance, knee score, and activity level took place; the majority were improved and declined surgery. A period of strength training is recommended before the decision to undertake surgery for cruciate ligament injury.

The reliability, validity, and responsiveness of the Lysholm score and Tegner activity scale for anterior cruciate ligament injuries of the knee
- 2009
-
In: American Journal of Sports Medicine. - : Sage Publications. - 0363-5465 .- 1552-3365. ; 37:5, s. 890-897
-
Journal article (peer-reviewed)abstract
- Background: In 1982, the Lysholm score was first published as a physician-administered score in the American Journal of Sports Medicine. The Tegner activity scale was published in 1985.Hypothesis: The Lysholm and Tegner scores are valid as patient-administered scores and responsive at early time points after treatment of anterior cruciate ligament tears.Study Design: Cohort study (Diagnosis); Level of evidence, 1. Methods: All patients were treated for an anterior cruciate ligament tear. For responsiveness, the Lysholm score (n = 1075) and Tegner activity level (n = 505) were measured preoperatively and 6, 9, 12, and 24 months postoperatively. For test-retest (n = 50), scores were measured at 2 years postoperatively and again within 4 weeks by questionnaire. For criterion validity (n = 170), patients completed the Short Form-12 and the International Knee Documentation Committee score in addition to Lysholm and Tegner instruments. For all other analyses, preoperative Lysholm score (n = 1783) or Tegner activity levels (n = 687) were collected.Results: There was acceptable test-retest reliability for both the Lysholm (intraclass correlation coefficient = 0.9) and Tegner (intraclass correlation coefficient = 0.8) scores. The minimum detectable change for Lysholm was 8.9 and for Tegner was 1. The Lysholm demonstrated acceptable internal consistency. The Lysholm correlated with the International Knee Documentation Committee (r = .8) and the Short Form-12 (r = .4), and Tegner correlated with the Short Form-12 (r = .2). Both scores had acceptable floor and ceiling effects and all hypotheses were significant. The Lysholm and Tegner were responsive to change at each of the time points.Conclusion: After 25 years of changes in treatment of anterior cruciate ligament injuries, the Lysholm knee score and the Tegner activity scale demonstrated acceptable psychometric parameters as patient-administered scores and showed acceptable responsiveness to be used in early return to function after anterior cruciate ligament treatment.

Concussed athletes are more prone to injury both before and after their index concussion : A data base analysis of 699 concussed contact sports athletes
- 2016
-
In: BMJ Open Sport and Exercise Medicine. - : BMJ Publishing Group Ltd. - 2055-7647. ; 2:1

Journal article (peer-reviewed)abstract
- Background: Ice hockey and football players suffering concussions might have an increased risk for injuries afterwards. We aimed to investigate if concussions predisposed athletes for subsequent sport injuries.Methods: Patient data were obtained from a data base established at the University Hospital in Umea, Sweden. Athletes who had suffered a concussion were included if they had been aged between 15 and 35 years of age, and played ice hockey, football (soccer), floorball and handball. They were studied in terms of all new or previous injuries during 24 months before and after their concussion. Results were compared with a control group of athletes from the same four sports with an ankle injury.Results: Athletes with a concussion were more likely to sustain injuries compared with the control group, both before (OR 1.98. 95% CI 1.45 to 2.72) and after the concussion (OR 1.72. 95% CI 1.26 to 2.37). No increase in frequency of injury was found after a concussion compared with before. This was true for athletes in all four sports and for both sexes.Conclusions: This study indicates that athletes sustaining a concussion may have a more aggressive or risk-taking style of play than their counterparts. Our data do not suggest that a concussion injury, per se, leads to subsequent injuries.

Varför ska du använda PROMIS? : Nytt system för patientrapporterad utfallsmått
- 2018
-
Conference paper (other academic/artistic)abstract
- PROMIS är ett itembanksystem för hälso- och sjukvården. Syftet är att erbjuda moderna, patientrapporterade mått som kan användas för flertalet patientgrupper till en mycket låg kostnad och med ett nationellt supportsystem.En itembankär en modern form av elektronisk enkät som kan innehålla ett stort antal enkätfrågor. Ett datorprogram väljer ut de mest lämpade frågorna till varje person utifrån dennes svar på föregående frågor, på så sätt enkäten individanpassas.
